Is calculations of L-pads based on "nominal impedance" or Re?

Hi,

I would like to make L-pads for my BMS 4592 ND drivers. However, I am not quite sure whether to base the calculation on the drivers "nominal impedance" (which is 16 Ohm) or their Re values, which according to the people at BMS are 8.9 Ohm for the "mid" section and 7 Ohm for the "tweeter" section.

I have actually heard both claims stated!? Could some of you tech-guys (Wayne P.?) please tell me which route is correct? Thanks!

Regards
Peter
